Comtrol eCos - Manual (Page 458)

Chapter 31. POSIX Standard Support
• All system variables supported by sysconf will yield a value. However, those that are irrelevant to eCos will
either return the default minimum defined in < limits.h > , or zero.

Functions Omitted

int mkfifo( const char ∗ path, mode_t mode );
int chmod( const char ∗ path, mode_t mode ); // TBA
int fchmod( int fd, mode_t mode ); // TBA

int ftruncate( int fd, off_t length ); // TBA
Notes
• If a call to open() or creat() supplies the third _mode_ parameter, it will currently be ignored.
• Most of the functionality of these functions depends on the underlying filesystem.
• Currently access() only checks the F_OK mode explicitly, the others are all assumed to be true by default.
